A514 steel plate is high strength weldable steel quenched and tempered according to ASTM standard. ASTM A514 steel plate is mainly used in places where steel plate a283 c high tensile strength and high yield are required. The lifting gears of engineering vehicles, and racks for offshore platforms generally use A514 grade Q or A514 Gr Q. The steel plate a283 c hardness of A514 steel plate is between 235-290. A514 steel yield strength is more than 630MPa, and tensile strength is more than 700MPa. A514 steel plate is difficult to process. In the United States, the use of A514 steel plate is very large.
The main raw material of steel plate a283 c, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.
When automatic steel plate cutting is carried out, the distance difference between the steel plate hanging from the steel plate to the gas cutting platform should be adjusted to within 5mm.When semi-automatic cutting is carried out, the guide rail should be placed on the plane of the steel plate to be cut, and then the cutting machine should be placed lightly on the guide rail.Make one side of the cutting torch face the operator, choose the cutting nozzle according to the thickness of the steel plate, adjust the cutting straightness and cutting speed.
